Update: Two More Cruise Lines Return to Egypt; Another Cancels Calls

(Updated 1 p.m. EDT) -- Two more lines have announced their return to Egypt since political unrest, which prompted more than a dozen lines to alter or cancel itineraries, has calmed.

Cosmos and Avalon Waterways, both Globus travel brands, canceled sailings through March but have since said they will resume voyages, beginning with Avalon's Royal Lotus on April 1.

Conversely, Sea Cloud's Sea Cloud will forego stops in Egypt on its November 16 sailing and will, instead, opt to sail a transatlantic itinerary from Lisbon to Antigua and spend the winter months in the Lesser Antilles, according to a statement from the line.

The U.S. Department of State still has a travel warning in place for Egypt and continues to advise against unnecessary travel to the country.
